DESCRIPTION
On-chip support is provided for all of the IMVP-6 requirements, including Active Voltage Positioning, Geyserville-3 VID transitions, VID-controlled Deeper Sleep voltage setting, PSI# and DPRSL control, fast/slow C4 exit, and default Boot voltage. Semtech’s proprietary Combi-Sense® technology provides a loss-less current sensing scheme which is extremely robust and easy to lay out. Eliminating the sense resistors reduces costs and PCB area, plus increases system efficiency. Integrated SmartDriver™ technology initially turns on the high side driver with ‘soft’ drive to reduce ringing, EMI, and capacitive turn-on of the low side MOSFET, while also increasing overall efficiency.
